I don't think this is true. I checked the stats for caloric supply and the highest value worldwide is (unsurprisingly) in North America where about 3,500 calories of food are produced per day. That is less than double what a person needs per day, so "several times" seems unlikely.
But I don't dispute the idea that we produce enough food to feed the world. But I also didn't say we didn't.
Could you comment on what I actually said, which is that an ageing population (or any situation in which there are more non-workers per worker) will result in less production being available for people on average?
This is not just about food; it is also about other necessities (such as healthcare) but also non-essentials like entertainment. The problem of an ageing population is not that we'll starve to death; it's that our quality of life will decrease.
That's not what I said. That site measures the output of the chain. I said we grow more food (ie plants) than humanity can eat. We feed the majority of that food to the livestock we keep that absolutely dwarfs the biomass of all wild animals. That introduces a 90%+ caloric inefficiency. If we just ate the plants, we would have to stop growing so much food, even all our industrial processes don't demand that much. But capitalism demands instead that we keep growing more food than the year before, and so it demands inefficiencies like animal ag. Any scarcity is entirely engineered. It's not an accident, it's by design. It is necessary to maximize investor return.
No, it's because people like eating meat. You may have noticed that people ate meat centuries ago before capitalism existed, and favoured it over other foods when it was available.
But I understand what you meant about growing multiples of food, now, so that's good.
This isn't just about food, but look at the number of people one farmer could feed 200 years ago (6 or so) vs today (150 or so). We spend a lot of our productive time today doing stuff we didn't have time for just a couple hundred years ago. We've got a long way to fall before we are unable as a species to meet our needs. Proponents of tech advances expect our productivity to increase even if the workforce shrinks. If our standard of living delines on average, either these prognosticators are incorrect or we have a huge allocation issue.
I think it is a problem if we need to have less free time, or work more for the same things that we do in our free time, because a higher proportion of worker time needs to be spent supporting people who are not working. You don't want to go back 200 years even if humanity could survive in such conditions. (And the present population probably could not survive)
